PRESSED-illi ETAL PUMP.

Specification of Letters Patent.

Patented Sept. 19, 1905.

Application filed February 28, 1905. Serial No. 247,798.

the United States, residing at Saginaw, in the county of Saginaw andState of Michigan, have invented certain new and useful Improvements inPressed-Metal Pumps; and we do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

Our invention relates to improvements in hand-pumps for house service,the objects be ing to produce a pump that is light and of suchconstruction that the pump body and base may 'be made of sheet metal andyet preserve the strength and rigidity of an ordinary castrnetal pump.

With these objects in view our invention consists in certain novelfeatures of construction and their equivalents described in thespecification and set forth in the claims.

In the accompanying drawings, Figure l is a perspective showing the pumpcomplete. Fig. 2 is a part vertical section through the center of thepump. Fig. 3 is a perspective View of the barrel, the funnel-shapedchamber, and the spout. Fig. 4 is a view of the cover. Figs. 5 and 6 areviews of the gasketplate which is secured between the barrel and thebase. Fig. 7 is a perspective view of the base. Figs. 8 and 9 are viewsof the pressed-metal pump-handle. Fig. 10 shows the funnel-shapedchamber developed. Fig. 11 shows the development of the spout. Fig. 12shows the development of the base.

A is the base, made of a single piece of sheet metal stamped out, asshown in Fig. 12, and pressed to the form shown in Fig. 7. It has threedownwardly-projecting legs a, formed integral with the flat top a. Eachleg has a beaded rib a, which gives it the necessary stifliness. Theflat top a has a central opening through which passes the suction-pipe.

B is a gasket-plate resting upon the base A and forming a tight jointbetween the base A and the flange (Z of the barrel D. The gasketplatehas a central opening 5, registering with the opening a of the base A.The half-nipple'b" has a shoulder 6' turned on it, the projecting end ofwhich extends up through the opening 7) in the plate and is headed overon the upper side, thus making a tight joint.

The suction-pipe C can be connected to the nipple b by a coupling 0 orother suitable means.

The barrel D comprises a sheet-metal cylindrical portion having aflanged base d, which is securely fastened to the base A by means of thebolts d. The top of the barrel is flanged out, as shown at (Z, to fitthe funnelshaped chamber E and is either beaded,brazed, or soldered toit.

The sheet-metal chamber E is shaped like an inverted truncated cone. Itsupper edge e is flanged in and forms an annularsupportingring, to whichthe cover G is bolted. An opening a in the side of the chambercommunicates with the spout F. The spout F is of sheet metal and is ofthe ordinary shape. It is secured to the wall of the chamber E bybrazing, soldering, or otherwise.

The chamber E is closed by the cover G, fastened by bolts 9 passingthrough the flange c. The cover is dished and its edges are flanged downaround the outside edge of the chamber E to make a tight joint andprevent the cover being displaced. The cover has a slotted hole g toreceive the plunger-rod R, and it also has two lugs or brackets g, whichsupport the handle H. These lugs are secured to the cover by rivets g orotherwise.

The handle H is of the general shape shown in Figs. 8 and 9 and isformed of two pressedv metal members fastened together by rivets h, asshown. I

The plunger I and the foot-valve K are the same as in an ordinarycast-metal pump.

This novel construction produces a pump that is much less expensive tomanufacture than the ordinary cast pump of the same capacity. It can bereadily taken apart for cleaning or repairing and is not liable to getout of order. In shipping long distances by freight its lightnessenables its selling and distributing area to be increased much beyondthat of the common cast pumps. Breakage in shipment or in use is almostentirely eliminated, and any part of the pump bent in shipment can beeasily straightened without the use of special tools.

What we claim as our invention, and desire to secure by Letters Patent,is as follows:

1. A cistern-pump comprising a base formed of a single piece of sheetmetal; a gasketplate resting upon the base, said gasket-plate having acentral opening; a downwardly-projecting nipple in said opening; afoot-valve carried by said plate; a barrel comprising a sheet metalcylindrical portion having a flanged base and having anoutwardly-flaring upper portion formed of sheet metal, the upper edge ofsaid flaring portion being flanged inwardly to form an annularsupporting-ring; a spout secured to said upper portion; a cover formedof sheet metal and having its edges flanged downwardly; sheet-metal lugssecured to said cover and a handle formed of sheet metal pivotallymounted in said lugs; together with a plunger connected to said handle,substantially as described.

2. A shell for cistern-pumps comprising a base formed of sheet metal; agasket-plate having a downwardly projecting-nipple; a cylindrical bodyformed of sheet'metal and having its lower end provided with a flange; afunnel+shaped chamber formed of sheet metal and secured to the upper endof said cylindrical body; a sheet-metal spout secured to said chamber; aflanged cover for said chamber formed of sheet metal; lugs secured tosaid cover and a handle pivotally mounted on said lugs, substantially asset forth.

3. A shell for cistern-pumps comprising a baseformed of sheet metal; agasket-plate having a downwardly-projecting nipple; a cylindrical bodyformed of sheet metal and having its lower end flanged outwardly; asheetmetal spout secured to said chamber; a flanged cover for saidchamber formed of sheet metal; lugs secured to said cover and a handlepivotally mounted on said lugs, substantially as set forth.

In testimony whereof we aflix our signatures in presence of twoWitnesses.
